Hawk,
I'm sorry that you find yourself in the position that you are currently in, but I disagree with those who tell you NOT to tell your doctor, I believe that you should tell him/her. First, I don't believe that any legitimate pain management doctor would have wanted their patient taking all of those immediate release oxycodone at one time. I think that you indeed have made an error or there is some type of misunderstanding in the way you are supposed to take those meds.
Secondly, there are options available to you, in the form of other long acting medications that can take that might very well help you with the pain and your addiction. Taking more than prescribed , for the euphoria is addiction, not a tolerance issue.
Suboxone is a good medication that can be and is used for the treatment of addiction, and also is being used for the treatment of chronic pain, at certain dosages. Many people that I have come across, have successfully used suboxone instead of the "traditional" opiates to treat both conditions.
Buprenorphine (suboxone or subutex) is also another medication that may be used to treat chronic pain...it is fairly new to the market but has good reports so far.....
Rehab is one thing that you can consider as well, and getting back into PT, using TENS, ice, heat, over the counter heat patches, anti-inflammatories, massage, and even accupuncture all can help to ease the pain, as well as visualizations, and tons of other things.
There is an implanted intrathecal pain pump- which delivers opiates, and when necessary, muscle relaxants, lidocaine type of meds, can all be delivered directly into the spinal canal, which allows for micro doses of the medications because they are spread throughout the spinal canal which allows the meds to get to the source of the pain much sooner and allows really good pain relief.
Your other option is a spinal cord stimulator- this is an implanted device that has leads that run parallel to the spinal cord, and similar to the TENS unit, causes an anesthesia of sorts to disrupt the pain signals.
So you do have options my new friend, you just need to have a very frank and honest discussion with your physician. He is there to help you and he will offer you many options, but only when you decide to be honest with him about what is really going on.....
